ABSTRACT:
A lid or cover for a ceramic enclosure is formed of a substrate of an iron-based alloy, e.g., Kovar, alternately plated and coated with electrolytic nickel and electroless nickel, with an outer gold electroplate. The alternate electroplate and electroless nickel layers render the lid highly corrosion resistant without the need for an expensive, unrecoverable buried gold layer.
